ShadowEdge turns YouTube, TED, TikTok, podcasts, or any audio file into structured shadowing practice. Paste a link or upload a file, and AI transcription splits the source into sentence-level segments with millisecond-accurate timing — no subtitles to copy, no transcripts to fix before practicing.
Learners listen to a sentence, record themselves, and get per-phoneme pronunciation feedback that shows exactly which sounds drifted and which sentence to repeat. Twelve practice languages are supported, including English, Japanese, and Chinese.
The platform runs on web, iOS, and Android, with the ShadowStudio Desktop companion for capturing and preparing your own source material. Libraries and progress sync across devices. ShadowEdge is operated under the GoShadowing brand.
